tJNlTLE S'lTATlilEl ARTHUR K. PHILLIPEI, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR TO \VESIING- HOUSE ELECTRIC 8:; MANUFACTURING CQMPANY, .A CORPORATION OF PENN- SYLVANIA.

TERMINAL commerce.

Application filed June 23, 1925.

My invention relates to circuit cornecters and particularly to connectors adapted for radio receiving ap iaratus.

An object of my invention to providev a terminal connector adapted to make an elastic coi'inection with terminal tips.

Another object of my invention is to provide an elastic connec or adapted to be attached to a radio panel for making; connection with a still terminal of a radio circuit.

Another object (it my invention is to pro ride a connecter having a portion adapted to be attached to an insulating panel. a secend portion adapted to be attached by soldering to circuit wires or connected apparatus, and having a pair of opposed arcuate arms adapted to make Contact With a still wire tip.

In the construction of radio apparatus, a number of methods-have been used for the connection of head phones and loud speals ers in the output circuit of radio apparatus.

These, however, have been found U115 'sfactory. The ordinary binding posts do not make a stiff connection with cord tips, but instead, a very slight sidewise pull will sengage the tip and break the circuit. As a substitute for standard binding posts, telephone jacks and plugs have been used, but these have been found undesirably expensive.

My invention provides a spring contact member which will make a tirm connection directly with cord tips and will resist a sidew'ise pull but may be easily released by direct withdrawal.

Other objects and structural details of my invention will be apparent from the followi description when read in connection with the accompanying drawiiu s, wherein Figure l is an end view oi an (.llllhltllllltlll of my invention;

Fig. 2 is a bottom plan view ol the con necter of Fig. l

Fig. 3 is a side View ot' the same;

Fig. l is an end View with a cord tip in place; and

Fig. 5 is a bottom View in perspective of the connecter.

The connector of my invention formed as indicated in the figures from a single stamping of sheet metal having a base portion 1, and openings 2 and 3 therein, for fastening screws. One end of the base 1 is Serial No. 38.970.

struck up to form a hug -l to Which a circuit vii-e may be soldered, thus forming a tail piece. The arcuate arm portimis 5 and (3 are formed into opposing elastic members. It third openinp 7 is provided for the insertion of the cord tip.

In the application of my connector, it may be attached to the untharside of a radio panel S, as indicated in Fig. 5, by means ol screws 0 and 10, in such position that an opening ll, through the panel 8 is ulined with the opening 7 in the base portion 1.. A conductor 12 may then be soldered to the lug -l and connected to other apparatus upon the panel. A still cord tip 14 to which may be attached a flexible conductor 15 may then be inserted through the openings 11 and T between the members and (3 whereupon it will be firmly held by spring friction and a firm Contact made thereto.

Vhile I have shown but a single embodiment ol my invention, in the accompanyinp' description, it capable of various modifications thererroln without departing from the spirit thereof and it desired therefore that only such limitations shall be imposed thereon as are required by the prior art or indicated in the appended claim.

I claim as my invention:

it ccnuecter lug comprising;- av shectunctal member having: a fiat body portion provided with holes through which fastening devices may extend to secure the lug in place on a that surface. a pair of resilient arms extending laterally from opposite sides of said body portion and extending at an angle to the plane of said body portion into pr ily to each other. said body portion haying a hole through which a conductor may be thrust to enter between the proximate portions or" said arms to contact with each ot them and said body portion also having: a lane on the side of one of said lirst-mimed holes opposite said arms and extending out of the plane of said body portion on the same side of said plane as the proximate portions of said arms whereby an additional connection to the lug may conveniently be made.

In testimony whereof, I have hereunto subscribed my name this 8th day of June, 1925.

ARTHUR K. PHILLIPPI.
